The Operational Meaning of Total Energy of Isolated Systems in General Relativity
We present thought experiments to measure the Arnowitt-Deser-Misner and
Bondi-Sachs energy of isolated systems in general relativity. The expression of
the Bondi-Sachs energy used in the protocol is likely to have other
applications. In particular, it is well-suited to to be promoted to an operator
in non-perturbative loop quantum gravity.
